Emergency Services and Safety Precautions
The standard, “Recommended Practice for
Determining the Spatial-Peak Specific
Absorption Rate (SAR) in the Human Body Due
to Wireless Communications Devices:
Experimental Techniques,” sets forth the first
consistent test methodology for measuring the
rate at which RF is deposited in the heads of
wireless phone users. The test method uses a
tissue-simulating model of the human head.
Standardized SAR test methodology is
expected to greatly improve the consistency of
measurements made at different laboratories on
the same phone. SAR is the measurement of
the amount of energy absorbed in tissue, either
by the whole body or a small part of the body. It
is measured in watts/kg (or milliwatts/g) of
matter. This measurement is used to determine
whether a wireless phone complies with safety
guidelines.
9. What steps can I take to reduce my
exposure to radio frequency energy
from my wireless phone?
If there is a risk from these products - and at
this point we do not know that there is - it is
probably very small. But if you are concerned
about avoiding even potential risks, you can
take a few simple steps to minimize your
exposure to radio frequency energy (RF). Since
time is a key factor in how much exposure a
person receives, reducing the amount of time
spent using a wireless phone will reduce RF
exposure. If you must conduct extended
conversations by wireless phone every day, you
could place more distance between your body
and the source of the RF, since the exposure
level drops off dramatically with distance. For
example, you could use a headset and carry the
wireless phone away from your body or use a
wireless phone connected to a remote antenna.
Again, the scientific data do not demonstrate
that wireless phones are harmful. But if you are
concerned about the RF exposure from these
products, you can use measures like those
described above to reduce your RF exposure
from wireless phone use.
10. What about children using wireless
phones?
The scientific evidence does not show a danger
to users of wireless phones, including children
and teenagers. If you want to take steps to
lower exposure to radio frequency energy (RF),
